What This Door Fits
This is the roadside center access door for Thermo King Precedent S-600, S-700, and C-600 series reefer units - the panel that gives you access to the condenser/compressor bay from the curb side. It's not the whole housing, just the door itself with hinge points and latch cutout matching the factory setup.
These doors take a beating from dock workers, branches, and guys who don't realize they're not built to lean a ladder against. Cracked corners, stripped hinge mounts, and latch failure are the usual reasons it gets replaced.
98-9640 is Thermo King's part number for this door across all three series - S-600, S-700, C-600 - so one door number covers a decent spread of units.
Why 98-9640 Crosses Clean
DR-011A and TK98-9640 both trace back to the same Thermo King print. Aftermarket houses stamp their own part number on it, but the hinge spacing, latch pocket, and panel dimensions are cut to the same spec as the factory door.
Where it can bite you: Precedent units got running changes over the years, and some early S-600 units used a slightly different hinge bracket before Thermo King standardized. If your unit is older or has had prior body work, check the hinge mounting holes on the housing before you order.
Surest way to confirm - pull the number off your old door if it's still legible, or give us the Thermo King unit serial number and we'll check it against the model year. Don't guess off the truck VIN alone since the reefer unit gets swapped separately from the chassis sometimes.
Ordering From PartStop
We stock this one in Tacoma - if you're local, same-day pickup is usually doable if you call ahead and it's still on the shelf. Otherwise it ships out same day for most of the West Coast and within a couple days everywhere else in the lower 48.
Comes with our standard 6+ month warranty. If it shows up and the hinge holes don't line up or the latch doesn't seat right, call us before you start drilling new holes - we'd rather sort it over the phone than have you modify a part you're going to return.
At $210.99 it's a straightforward swap for most guys with basic hand tools - no special jigs needed, just matching up the hinge bolt pattern.

Frequently asked questions
Does 98-9640 fit my Precedent unit?
Should fit S-600, S-700, and C-600 series units where that's the door number stamped on the old part or listed on your unit's data plate. Give us the reefer unit serial number and we'll double check before you order - unit swaps happen and the wrong door number can end up on a truck.
Is DR-011A the same as the Thermo King TK98-9640?
Same panel dimensions, hinge spacing, and latch cutout - built off the same print. It's not sold as a genuine Thermo King part, it's the aftermarket cross. Functionally it does the same job; just confirm your hinge bracket matches before installing, especially on older S-600 units.
What if the door doesn't fit right?
Call us first. Most mismatches come from an older unit with a different hinge bracket than what standard 98-9640 units use. We can usually figure out over the phone whether it's a fit issue or something in the housing that needs attention - don't force it or drill new holes without checking with us.
